02.

On the graphs (North or South) supplied in the PF kit instruction man-
ual, locate the curve for the location’s

latitude

(

e.g: 45°N)

03.

Choose the

period of the year

on which to base the calculation, or

select the lowest point of the curve to calculate

the worst period of

the year;

then read the corresponding value

(e.g. December,

January: Am= 200)

04.

Calculate the value of energy available

(produced by the panel)

multiplying

(example: Ea = 14; Am = 200, i.e. Ed =

2800)

• Calculating the energy consumed

To calculate the energy consumed by the automation, proceed as follows:

05.

On the table below, select the box corresponding to the intersection
between the line with the

weight

and the column with the

opening

angle

of the leaf. The box contains the value of the

severity index

(K)

for each manoeuvre

(

e.g.

gearmotor with standard arm on leaf of 130

Kg and 95° opening; K = 84)

06.

On the

table 4,

select the box corresponding to the intersection

between the line with the

value and the column with the

value.

The box contains the maximum possible number of cycles per day
(e.g.

Ed= 2800; K= 84; cycles per day = 30)

If the number obtained is too low for the envisaged use or is located in the
“area not recommended for use”, the use of 2 or more photovoltaic pan-
els may be considered, or the use of a photovoltaic panel with a higher
power. Contact the Mhouse technical assistance service for further infor-
mation.

The method described enables the calculation of the maximum possible
number of cycles

per day

that can be completed by the automation while

running on solar power. The calculated value is considered an average
value and the same for all days of the week. Considering the presence of
the battery, which acts as an energy “storage depot”, and the fact that the
battery enables automation autonomy also for long periods of bad weath-
er (when the photovoltaic panel produces very little energy) it may be pos-
sible to exceed the calculated maximum possible number of cycles per
day, provided that the average of 10-15 days remains within the envis-
aged limits.

Table 5

specifies the maximum possible number of cycles, according to

the manoeuvre’s

severity index

(K), using

exclusively the energy stored

by the battery. It is considered that initially the battery is completely
charged (e.g. after a prolonged period of good weather or recharging via
the optional PCB power supply unit) and that the manoeuvres are per-
formed within a period of 30 days.

When the battery runs out of the stored energy, the led starts to indicate
the battery low signal by flashing briefly every 5 seconds, accompanied by
a “beep”.

If the “WT” is used on a single leaf gate (with only one gearmotor), the
maximum possible number of cycles corresponds to the value in the
tables, multiplied by

1.5.

For example, if the calculated number of cycles

is 30 and the gate has one leaf only, the number of cycles will be: 30 x

1,5

= 45.

A.6 - “Stand-by” function when the device PR2

and/or PF is installed

(optional devices)

When the automation is powered by the backup battery PR2 or the pho-
tovoltaic system PF, the “standby” function is activated automatically 60
seconds after completion of an automatic manoeuvre cycle. This turns off
the “ECSbus” output and all connected devices, the outputs “Flash”, “Els”
and all leds, with the exception of the ECSbus led which flashes more
slowly (1 flash every 5 seconds). After this, as soon as the user sends a
command, the control unit restores power and starts the manoeuvre

(this

may start with a short delay).

A.7 - Using the “ECSBus” input/output

Only devices compatible with ESCBus technology must be connected to
the terminal “ESCBus” (this is explained in detail in paragraph 3.3.3).

Important

– Following testing of the automation, each time new

devices are connected to (or removed from) the “ECSBus” terminal,
the learning procedure must be performed as described in para-
graph A.10.

A.8 - Using the “STOP” input

STOP is the input that causes immediate shutdown of the manoeuvre
(with brief inversion). This input can be connected to devices with contact
types Normally Open (NO, as in the case of the KS100 selector switch),
Normally Closed (NC) or devices with a constant resistance of 8.2 K

such as sensitive edges.
When set accordingly, more than one device can be connected to the
STOP input, also different from one another. For this function, refer to

Table 6

and the following notes to the table.

Note 1.

The combination NO and NC is possible by connecting the 2
contacts in parallel, taking care to connect a 8.2k

resistance to

the NC contact (this enabling the combination of 3 devices: NO,
NC and 8,2k

Note 2.

Any number of NO devices can be connected to each other in
parallel.

Note 3.

Any number of NC devices can be connected to each other in
series.

Note 4.

Two devices with a 8,2k

constant resistance can be connected

in parallel. However if there are more than two of these devices,
they must be connected “in cascade” placing only one terminat-
ing resistance of 8,2k

Warning!

– If devices with safety functions are connected to the “STOP”

input, only devices with a constant 8,2k

resistance output can guaran-

tee fault safety category 3.
